MACHINE FOR LEATHERING T'ACKS.

To all whom it may concern:

Be it known that I, CHARLES L. RUSSELL, of Derby, in the county of NewHaven and State of Connecticut, have invented a new and useful Machinefor Leathering Tacks or Nails; and I do hereby declare that thefollowing is a clear and exact description of the construction andoperation of the same, reference being had to the accompanying drawings,making a part of this specification, in which Figure 1 is an isometricalview of the whole machine, Figs. 2, 12, 7 are isometrical details; Figs.8, 4, 5, 6, 8, 9, 10, 11, 13 and 14, are plan and side views of details.

The same letters and figures represent the same parts in all thefigures.

The object of my invention is to provide a machine wherein the severaloperations of separating, distributing and conducting the tacks to aproper position for being leathered, and of driving the tacks throughthe leather, cutting out the leathered disks and discharging theleathered tacks shall be performed automatically and continuously withunerring certainty.

Z, represents the frame; F, the shaft; A, B, C, D, and E, cams; L, punchfor cutting the material; M, a die; T, T, slide and lever for movingforward die M; K, K, slide and lever for moving forward punch L; P, acurved tube terminating at stop V; J, J, feeders for feeding leather; X,inclined race; A, groove or slot in the inclined race; I, slide forholding feeders; H and G, slide and lever for operating feeders; O, N,punches; Q, an inclined groove or slot in slide U; 3, a stand forholding the lower end of stop V, through which V, slides by means of arm4, working in slot Q; 6, 6 tack separators; W, V, stop fingers; 5 fork;S S S S, connections; Q, cross head for operating stop fingers W, W; 8,stand through which lower end of fork slides; 9, stand for holding endof slide S; R, R, lever and projection for working slide S; M, hole indie M, for admitting point of tack; 10, 10 stands for holding die M; D,D, stand for holding lower end of lever B; B, B, a, c, I), b, 15, 16,springs.

Having given the names, letters and figures of the difi'erent parts ofthe machine, I will now proceed to show its construction and operation.

An apparatus not shown in. the drawings conducts the tacks to theinclined race X, into which they are introduced, hanging by their heads,their points hanging down in the groove A, the separators 6, 6 all opento receive the head and body of the tack. It will be observed that theseparators 6, 6 are divided, a portion Working above the plate of theinclined race X, for the purpose of grasping the head of the tack, and aportion of the same working under the plate for the purpose of takinghold of the body of the tack. The shaft now makes a half revolution; theprojection on cam C, (at 20, Fig. 6) raises the lever (the lower end ofwhich is hung in the stand D, D,) by contact with projection R, on leverB, which by slide S, and connections S, S S, S, gives to the feed endsof the separators 6, 6 a downward circular motion (upon their centers17, 18) carrying a tack with them. Then at or near their full stroke atack is disengaged which slides forward. to the stop finger IV, whichlies across the groove of race X, and there remains until the shaft hasmade another half revolution, when the stopfinger W, is withdrawn bymeans of the projection 20, on cam C, passing the projection R, on leverB, but not until the finger 7', (which is arranged by the side of thestop finger W, and working alternately with finger W, by means of crosshead Q, and connection S) is nearly or quite across the groove in raceX. The tack now rests against finger W, when another half revolution ofthe shaft withdraws finger W, and lets the tack drop from the end ofrace X, onto the fork 5, (which fork has just been driven into andacross or through the curved tube P) upon which the tack hangs by itshead, the point down, and entered into the curved tube P (see Fig. 7)ready to be dropped by fork 5, point foremost to a horizontal positionto be stuck. It is not the ofiice of the fingers W, W, to separate thetacks one from another, but to insure their dropping precisely at thetime required, as the tack has the time of a whole revolution of theshaft after leaving the separators 6, 6, before it is dropped onto thefork 5. Now another half revolution of the shaft takes place, whichwithdraws fork 5, (by means of connection S and springs B, B, theprojection on cam C, having passed the projection on lever B) and dropsthe tack through the curved tube P into the horizontal tube or groove P.The arrangement of fork 5, is such that the upper surface of the rods orprongs thereof 5, 5, shall be somewhat lower than the top of theinclined race X, so that when the tack drops from the race X, to thefork 5, the point of the tack shall be lower than the bottom of thegroove in race X, thus preventing (when the fork is withdrawn) the pointof the tack from striking the bottom of the groove, turning over andfalling head foremost into the curved tube P.

The construct-ion of the tube is as follows: Sufficient curve is givento the tube or pipe so that a tack suspended by its head falling by itsown gravity or being forced through it shall change from a perpendicularto a horizontal position; the tube P for convenience is joined to ahorizontal tube P, in which punch O, works, but the tube P, is notabsolutely necessary as a V shaped or half circular groove placed underand detached from the curved tube P, would answer as well to receive thetacks from the curved tube P (see Figs. 13 and 14). The cap which holdsthe punch L, and the end of horizontal tube P, in their places, is leftoff in the drawings in order to show the parts well.

The hollow punch L is arranged so near the receiving tube or groove P,as shall cause a full disk or head of leather to be cut when the leatheris moved the diameter of a'disk or head from the point where the leatherreceives the tack. The leather or material to be punched is first putthrough the slide I, far enough to cover the end of tube or groove P, infront of the stop V. The punches O, N, are drawn back by a spring 0, 0,attached to the slide U, which connects with slide 12, which holds thepunches O, N, the end of punch N, being back of the junction of tubes Pand P. The tack is now lying in the tube or groove P, the point againstthe stop V, which is forced up and covers the end of P, by means of arm4, worked by the slot 2, in the slide U, (see Fig. 2,) which is drawnback with the punches O, N, to which it is attached by slide 12. Theshaft now turns, the feeders J, J, move back out of the way of the punchL, by means of a spring 5, Z), which is broken away to show the otherparts, cam A, slide H, feed lever G, and slide I. The die M, moves up tothe leather by means of cam E, slide T, and lever T. The hole N in thedie M, is now opposite the tube P. The slide 12, slide U, and punches O,N, now move forward by means of cam B. Stop V, is forced down (by theinclined slot 2, in slide U) and dwells at the proper height to steadythe point of the tack while punch 0, drives it into the center of theleather, the tack lying on the end of stop V, by its own gravity, Fig.'12, when the point of the tack has entered the leather the stop V, isforced down out of the way of the head of the tack and the punch O, (bythe inclined slot 2, in slide U). The punch 0, does not drive the headof the tack quite up to the leather but leaves space enough between theleather and head of the tack for the feeder J, to pass between theleather and head of the tack and strike the body of the tack (Fig. Thedie M, punches O, N, and L, now move back from the leather by means ofthe springs 15, 16, 19, and 0, c, leaving the tack sticking through theleather. The stop V, now comes up and closes the end of P, ready to stopthe next tack. The feeders J, J, are arranged on both sides of theleather (Fig. 3) now move forward (by means of cam A, slide H, feedlever G and slide I) and striking against the tack feeds along theleather so if by any means there should be no tack driven through theleather there will consequently be no leather fed. The tack and materialare now brought opposite the punch L, the feeders J, J, now move backout of the way. The die M, moves forward, the point of the tack entersthe die, the punch L, moves forward by means of the cam D, slide K, andlever K, and cuts into the leather just far enough to hold the leatherfirm, and then stops until the punch N, comes forward and completes thedriving of the tack, at the instant the driving is finished a projectionon cam D, (24 Fig. 4) moves forward the hollow punch L, which cuts outthe disk, from the leather. The punch N, now drives the leathered tackinto and out of the lower side of the die M, which has an opening forthat purpose at 21, Fig. 8.

What I claim as my invention and desire to secure by Letters Patentis- 1. One or more separators 6 6 having a cavity in their ends or anequivalent therefor, which shall grasp the head or body of the tack, orboth, substantially as and for the purposes herein described.

2.
